Marion & Mariana | Live Selling Commerce & Resale Strategy

I connect inventory, visual presentation and performance so every selling channel works together as one clear, distinctive commercial experience.
Services
THREE PILLARS, ONE COMPLETE CYCLE

source, sell & rotate

I help businesses turn stagnant stock into moving revenue. Request, trade, and move unsold stock through our private The Trade Room group, source new inventory internationally, and fill the gaps in your market before your competitors do. Nothing sits still. Every piece of inventory remains commercially relevant and in motion.
COMMERCE DIRECTION
I help you shape how products are selected, presented and experienced according to your vision and target audience. This includes visual merchandising, host coaching & styling, product storytelling, live staging, and creative direction, ensuring every selling environment feels intentional and aligned with the brand.


ANALYSE & OPTIMISE
I review your sales, audience behaviour, and product performance to show you exactly what's working, what's costing you money, and what needs to change before it eats into your margins. These insights shape your stock decisions, live formats, pricing, and growth strategy. I help you cut wasted time and inefficient processes, and train your team to the highest level of product knowledge, so every online, offline or live session performs at its best."

The Trade Room
Move what isn't selling.
Find what your customers want.
A private, members-only trading network where verified resellers and businesses can move unsold stock, discover sourcing opportunities and connect with trusted industry sellers.
Hi, I’m Mariana!
With over 13 years of experience across luxury, resale, authentication, marketplace operations, design and art direction. I help fashion, jewellery and second hand businesses build a distinctive visual identity, strengthen their inventory and connect with the right audience. Through my services, I combine product curation, visual branding, live commerce, staff training and sales strategy to help businesses decide what to sell, how to present it and how to create a memorable world around their shop, brand and products. I remain personally involved in every project, bringing my experience, judgement and creative direction to every stage. I intentionally work with a limited number of clients, so each business receives direct access, thoughtful attention and a genuinely tailored approach, with no one size fits all solutions. So, let’s get started ! Let’s grow together !
